BTW, last night I found my old AM/FM radio that I haven't used for more than ten-years, at least. I set it to the AM band and walked around a bit listening to both the upper and lower bands between stations. It actually works as a very crude interference collector! I was able to hear interference from the powerline adapter itself at about 15-cm. Farther away than that it was undetectable. I followed the in-wall power wires and didn't pick up anything. The Visio flat-screen television was much noisier than the powerline adapter, as was the microwave oven, even with it not cooking anything. I should make a more detailed survey sometime. Granted, using an AM radio like this isn't a true field strength meter, but it's still a data point. The neighbor's SSB interference would have boomed in, swamping even 50-Kw clear-channel AM stations.
An AM radio wouldn't have a hope of detecting interference at the VHF and higher frequencies. AM runs roughly 500 KHz to 1.5 MHz. As for your neighbour, unless they're operating on the 160 M band, their transmissions will be at a higher frequency than AM. This means the problem is either the AM radio is unable to tolerate the strong signal, which indicates a flaw in the radio, or there is external mixing going on. If there was a fault with the transmitter, it would generate harmonics, which are even further from the AM band. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
